We adapted the Stochmon box to include LP filters at 1.8Hz behind the RMS parts.
Then measured the RMS signals for different RF signal levels at 11.0.65, 29.5, 55.325MHz provided by a RF freq. generator.
As you can see in the data below the suppression of the BP filters of neighboring frequencies is only 35-35dB in power (see also manufacturer specs).

We therefor want to substract crosstalk, by calculating it out. We decided to use C-code in CDS. No computer crashing this time :)

We however ran into the problem that the RMS signal channels are acquired by the slow (EPICS) maschine c1iool0. Channels are (C1:IOO-RFAMPD_33MHZ , -"-133MHZ, -"-166MHZ) and we could not access those in the CDS c1ioo model. Using the EpicsIn block we got an CA.Exception stating that the variable was hosted on multiple servers. We then tried to use the EzcaRead to access the variables. Got an compile error, about the compiler not beeing able to connect all parts. It seems that the EzcaRead left behind a "ghost" part in the model (something with M1:SYS-FOO_BAR which is the default naming of the EzcaRead block) even after we deleted that block. We toyed around with the /opt/rtcds/caltech/c1/chans/daq/C1EDU_IOO.ini  and  /cvs/cds/caltech/target/c1iool0/ioo.db  files. We tried to uncomment the "old" (33,133,166) channels there to get rid of the conflict, but that didn't work.

We want to write the outputs to C1:IOO-RFAMPD_11MHZ , -"-29MHZ, -"-55MHZ EPICS channels.

We had to get the model back from the svn to get it running again.
